Nick and I have been having a little debate over whether it is hard to eat healthy when one is poor. I say that the poor have a hard time eating well, because they have to shop sales, eat at fast food, and are dependent oftentimes on the corner store instead of a farmer's market. Nick says it is merely a matter of priorities, and it is possible to eat well on little money if you make it a priority. So, I found this article to be an interesting addition to the debate. It discusses how to eat for about $0.33 per meal, by shopping smartly and choosing your foods carefully.
My own experience, and those of my family, still indicate it is hard for the average person of low means to eat well. But this article certainly makes the argument that it is possible, if you have the time and energy.
